Alain Volmat 810251b0d3 clk: st: clkgen-mux: search reg within node or parent 
In order to avoid having duplicated addresses within the DT,
only have one unit-address per clockgen and each driver within
the clockgen should look at the parent node (overall clockgen)
to figure out the reg property.  Such behavior is already in
place in other STi platform clock drivers such as clk-flexgen
and clkgen-pll.  Keep backward compatibility by first looking
at reg within the node before looking into the parent node.

Stephen Boyd 62e59c4e69 clk: Remove io.h from clk-provider.h 
Now that we've gotten rid of clk_readl() we can remove io.h from the
clk-provider header and push out the io.h include to any code that isn't
already including the io.h header but using things like readl/writel,
etc.

Found with this grep:

I also reordered a couple includes when they weren't alphabetical and

that driver doesn't use clk consumer APIs.

Javier Martinez Canillas 4e907ef6bd clk: Replace explicit clk assignment with __clk_hw_set_clk 
The change in the clk API to return a per-user clock instance, moved
the clock state to struct clk_core so now the struct clk_hw .core field
is used instead of .clk for most operations.

So for hardware clocks that needs to share the same clock state, both
the .core and .clk pointers have to be assigned but currently only the
.clk is set. This leads to NULL pointer dereference when the operations
try to access the hw clock .core. For example, the composite clock rate
and mux components didn't have a .core set which leads to this error:

Unable to handle kernel NULL pointer dereference at virtual address 00000034

Gabriel FERNANDEZ ab35dc139a clk: st: Support for A9 MUX clocks 
The patch supports the A9-mux clocks used by ClockGenA9

A9-mux clock : Multiplexer inside ClockGenA9. A9 clock can be driven by
either PLL or External clock (with an optional divide-by-2). This is
implemented as 3-parent clock : PLL, Ext-clk OR Ext-clk/2

Gabriel FERNANDEZ 44993d3840 clk: st: Support for VCC-mux and MUX clocks 
The patch supports the VCC-mux and MUX clocks used by ClockGenC/F

VCC-mux clock : Divider-Multiplexer-Gate inside ClockGenC/F
It includes support for each channel : 4-parent Multiplexer, Post Divide
by 1, 2, 4 or 8, Gate to switch OFF the output channel. The clock is
implemented using generic clocks implemented in the kernel clk_divider, clk_mux,
clk_gate and clk_composite (to combine all)

MUX clock : 2-parent clock used inside ClockGenC/F. The clock is implemented
using generic clocks implemented in the kernel clk_mux.

DIVMUX clock : Divider-Multiplexer-Gate inside ClockGenA(s)
It includes support for each channel : 3-parent Multiplexer,
Divider for each Parent, Gate to switch OFF the output channel. The
clock is implemented using generic clocks implemented in the kernel

PreDiv clock : Fixed Divider Clock used inside ClockGenA(s) to divide
the oscillator clock by factor-of-16. The clock is implemented using
generic clocks implemented in the kernel clk_divider.
